General Description

: The NTE1509 is a monolithic integrated circuit in an 18–Lead DIP type package that senses analog voltage levels and drives 10 LEDs, LCDs, or vacuum fluorescent displays, providing a logarithmic 3dB analog display.

A single pin changes the display from a bar graph to a moving dot display.

LED current is regulated and programmable, eliminating the need for current limiting resistors.
